meaning of Q_bias ADMIXTURE bootstrap

Question

[samuelandjw]

I'm referring to the software ADMIXTURE by DH Alexander. I want to use -B option of ADMIXTURE 1.3.0 to calculate confidence intervals for admixture proportions. The results include a .Q_se file (I assume “se” stands for standard error) and .Q_bias. However, I cannot find the meaning of .Q_bias in all three papers on ADMIXTURE or the latest software manual.

What is the meaning of .Q_bias?

Thanks!

Hi Samuel,

Did you figure out how to interpret the Q_bias file? I ran admixture with the bootstrap option but it is not clear to me how to interpret this output to choose the best K.

Thanks,

No. I haven't figured it out yet.
